Hypoint proclaims, “We make zero emission air transport possible.” They do this by, “Building a next generation hydrogen fuel cell system that can deliver “Both high specific power: “2,000 Watts/kilogram and high energy density “1,500 Watt-hours/kilogram Exactly what aircraft designers are looking for.” These numbers exceed what the best batteries can manage at this time, and according to the company’s white paper, even better performance is on the way. Batteries vs. Fuel Cells Hypoint proclaims, “The age of zero-emission aviation is currently being prevented by the industry’s reliance on Li-ion batteries, which have a fundamental barrier at the chemistry level.” The firm limits cell performance to 200 Whr/kg, although Bye Aerospace claims 260 Whr/kg for their full battery packs, battery management systems and all.
